摘要: We examined N2O emissions from the rhizosphere of field-grown soybeans during late growth stage (99-117 days after sowing). Marked were detected nodulated root systems soybeans, whereas a non-nodulating soybean mutant showed no emission. Degraded nodules exclusively generated N2O. A culture-independent analysis microbial communities Bradyrhizobium sp., Acidvorax facilis, Salmonella enterica, Xanthomonas Enterobacter cloacae, Pseudomonas putida, Fusarium nematodes, and other protozoans to be more abundant in degraded nodules, suggesting that some these organisms participate emission process rhizosphere.
